It shouldn't be possible.
The United States Visitor and Immigrant Status Indicator Technology (US-VISIT) Program is an integrated, automated entry and exit capability that records the arrival and departure of any person not a citizen or national of the United States. US-VISIT conducts certain terrorist and criminal checks and verifies identities through comparison of biometric identifiers from a variety of systems. The databases checked include the Consolidated Consular Database (CCD) which stores biometric and biographic records of all who apply for visas and logs all refusals. A person attempting to enter the US via the Visa Waiver Program (VWP) with a current visa refusal logged on the CCD should be flagged for immediate deportation.
